1 Name: Date: Pd. Photosynthesis WebQuest Type in the following link: Read the introduction entitled Illuminating Photosynthesis by Rick Groleau Right-click on the button that says, Launch Interactive and choose Open in New Window option. When the new window opens read the introductory poem. Click on The Cycle at the top of the box 1. Click on each of the following items, and explain what happens: a. The shade over the window: b. The container of water: c. The child: 2. a. What gas does the child provide for the plant to use? b. What gas does the plant provide for the child to use? c. Will the plant continue to produce this gas if the shade over the window is closed? 3. According to this animation, what 3 main things does the plant need for photosynthesis to occur? (1) (2) (3) Click on The Atomic Shuffle at the top of the box. Read the introductory poem, and click on next 4. What type of molecule is shown in the leaf? 5. Draw one of the molecules to the right, as it is shown in the leaf. According to the reading, these molecules do not come from the tap. What two places do they come from? (1) (2)

2 Click on next and watch carefully. You may click on replay to watch this again. 6. a. What is stripped from each water molecule? b. From where does the cell get the energy to do this? c. The stripped molecules form pairs. Where does it go after this? Click on next 7. a. What gas enters the leaf? b. This gas enters through holes in the leaf. What are they called? Click on next 8. What molecule is formed once again? Click on next 9. Another molecule is formed ( and boy is it sweet ). What is the chemical formula? 10. What is the name of this molecule? Click on next and then note about this equation. 11. Write down the simpler version of the chemical equation for photosynthesis.

3 Click on Three Puzzlers at the top of the box. 12. Answer each of the following questions, and explain in your own words. a. Can a tree produce enough oxygen to keep a person alive? Explain.. b. Can a plant stay alive without light?. c. Can a plant survive without oxygen? Explain..

4 II. Overview of the whole process of photosynthesis. 1. Let's review all the raw materials needed for photosynthesis. Go to the following site: 2. Click on Launch Friz TV 3. Click on the Factivity on the left side of the screen and choose a plant from the options. Record two things that Liz (the dinosaur) does to make the plant grow. a. b. 4. What gas causes the plant to sigh? 5. What happens when the sun button is pushed? 6. Click on Liz and explain how Liz and the plant are helping each other. 7. Now click on "The Facts" button and answer the following questions by reading the dialog between Ms. Frizzle and Ms. Chlora. a. What are the plant veins called which transport water? b. What are the openings that allow carbon dioxide into the leaf? c. What is the plant's main nutrition source? d. What waste product of plants benefit humans?

5 Cellular Respiration: Part I: Function and equation for respiration: 1. Go to: Use the information provided to write a definition of cellular respiration in your own words. 2. Go to: Write the chemical equation for cellular respiration. What are the reactants? What are the products? Where have you seen something like this equation before? Explain. 3. How does the equation for cellular respiration compare with the equation for photosynthesis? 3. Go to: What is ATP? Why is it an important product of cellular respiration? Part II: Main Site of Cellular Respiration: Use the following link: to answer questions 5-7: 5. What is the main site of respiration in the cell? 6. Draw a picture of the respiration site and label major parts on the right. 7. What energy molecules are produced in this respiration organelle?

6 8. Go to: What is the difference between aerobic and anaerobic cellular respiration? 9. Click on the link and scroll down to fermentation. Under the photo, click Read more. School/section/2.16/ 10. What is lactic acid fermentation? Where does it occur? 11. What does a build-up of lactic acid cause? 12. What is alcoholic fermentation? 13. Why would an organism prefer aerobic respiration as opposed to anaerobic respiration (fermentation)? 14. Click on the link and scroll down to fermentation. Under the photo, click Read more. School/section/2.15/ 15. Give three ways that photosynthesis and respiration are dependent on one another.
